Mexican War (1846-1848)

The Mexican War was caused by the annexation of Texas by the United States in 1845. Most volunteer regiments were from southern states. Records of Mexican War veterans might exist in a state where the veteran later resided.

Mexican War Index to Pension Files, 1887–1926. (NARA T317). FHL films 0537000–13 Alphabetically arranged and includes the veteran’s name, rank, and unit; names of dependents; date of filing and application; certificate numbers; act filed under; and state from which application was made.

Civil War (1861 to 1865)

See Wyoming in the Civil War for information about Wyoming Civil War records, web sites, etc. with links to articles about the Wyoming regiments involved in the Civil War.

The regimental pages often include lists of the companies with links to the counties where the companies started. Men in the companies often lived in the counties where the companies were raised. Knowing a county can help when researching more about the soldiers and their families.

The Civil War Soldiers and Sailors System allows name searching for soldiers. The result set gives the regiments for the soldiers. Then you can check the Wiki regiment pages to determine counties. Often knowing the counties that had men in a regiment will help you determine if a soldier was your ancestor.

Indian Wars (1780s-1890s)

Enlistment registers are available for soldiers who served in the regular army from 1798 to 1914. Many of these soldiers served in the western states, including Wyoming, during the Indian wars. The enlistment registers provide the soldiers' rank, unit, commanders, physical description, occupation, and birthplace. The records are arranged by year and by the first letter of the surname (Family History Library films 350307—).

An index is available for soldiers who applied for pensions between 1892-1926, as a result of service in the Indian Wars which were fought between 1817 and 1898 (Family History Library films 821610-21). The pension records are only available at the National Archives.

Historical accounts of the forts and posts in Wyoming are in Robert A. Murray, Military Posts of Wyoming (Ft. Collins, Colorado: Old Army Press, 1974).

Spanish-American War (1898)

The Spanish-American War was largely fought in Cuba and the Philippines. Spanish-American War records might exist in the state from which the soldier served or in a state where the veteran later resided.

A published roster of soldiers is in volume one of Ichabod S. Bartlett, Editor, History of Wyoming, Three Volumes. (Chicago, Illinois: S.J. Clarke Publishing Company, 1918; Family History Library film 1000826 items 2-4).
